According to the theoretical basis of thermokinetics,the thermokinetic equations of parallel first order reactions and parallel first and second order reactions have been derived,and the mathematical models for determining the kinetic parameters for parallel reactions from the thermoanalytical curve have been established in this paper.In order to test the validity of this method,two simulated parallel reaction systems (saponification of mixed esters in aqueous ethanol solvent) have been studied.The rate constants calculated by this method are in agreement with those published in literature,and therefore,the thermokinetic equations derived in this paper for parallel reactions is believed to be correct.
